Dell has revamped its OptiPlex desktop line, pitching its latest offerings as less power-hungry beasts than before - and easier to tinker with than its rivals' products.

Dell's OptiPlex 760 (top) and 960: you want cases, we got 'em

Take the OptiPlex 960, for example. It consumes 43 per cent less power than its predecessor, Dell claimed, and can be serviced in just over two-thirds of the time it takes to fiddle with "a comparable system from HP".

Servicing one takes 43 per cent less time than servicing a comparable Lenovo machine, Dell added, and it made similar claims for all the latest OptiPlex machines, the 760, 360 and FX160.

Between them, the four OptiPlex lines cover the gamut of form-factors - compact, desktop and mini-tower - and are available with an array of Intel processors, memory, storage and optical drive options for IT staff to choose from.
